Boeing 747-400 vs. Airbus A340-200

The Boeing 747-400, a major development in the iconic 747 series, debuted in 1988 and quickly became one of the most recognizable aircraft in the world. Known as the "Queen of the Skies," this wide-body airliner redefined long-haul travel with its unparalleled range and capacity.

With a commanding presence, the 747-400 stretches 231.9 feet (70.7 meters) in length and boasts a wingspan of 211.4 feet (64.4 meters). The -400 featured reinvented wingtip extensions and winglets which improved the aircraft's fuel efficiency by 4%. Its distinctive second floor hump and four-engine configuration make it a standout at any airport. The 747-400's design accommodates up to 416 passengers in a typical three-class layout, making it one of the largest passenger airliners at the time of its introduction. The -400 variant was later succeeded by the newer 747-8I.

The 747-400 had three engine options; Pratt & Whitney PW4000s General Electric CF6s, or Rolls-Royce RB211s. Each 747-400 had a thrust of about 56,000 lbf (249.0 kN), summing up to an impressive total of 224,000 lbf (996.0 kN) across the 4 powerplants. This immense power, coupled with a fuel capacity of 57,061 US gallons (216,000 liters), allows the 747-400 to achieve a range of 7,284 nautical miles (13,490 kilometers). This exceptional range capability opened up numerous long-haul and transoceanic routes, reducing the need for stopovers and changing the face of international travel.

In the commercial aviation market, the Boeing 747-400 was a direct competitor to other large aircraft such as the Airbus A340. However, its unique features, like the upper deck and expansive cargo capacity, gave it a special place in the hearts of aviation enthusiasts and professionals alike. The 747-400 was operated by airlines such as British Airways, Qantas, Lufthansa, United Airlines, and Air France. These were among many other operators that used the 747-400 for their flagship international routes. Its spacious cabin and long-range abilities made it ideal for high-profile and high-density routes, offering passengers a unique and comfortable flying experience.

The Boeing 747-400's legacy goes beyond its impressive technical specifications. It symbolizes a significant era in aviation history, where the pursuit of connecting distant parts of the world became a reality. The aircraft's production, which spanned over two decades, is a testament to its enduring appeal and the pivotal role it played in shaping modern air travel. Today, while newer, more fuel-efficient aircraft have started to replace the 747-400, its iconic status and contribution to the airline industry continue to be celebrated. The Boeing 747-400 remains an enduring symbol of the romance and grandeur of flying, representing a bygone era of luxury, scale, and ambition in aviation. Lufthansa, Air China, and Asiana Airlines are some of the last airlines to hold onto their last 747-400s.

The Airbus A340-200 is a long-range, wide-body aircraft, part of the A340 family known for its four-engine configuration. Introduced in 1992, the quadjet was designed to meet the demands of long-haul flights. The A340-200 has a longer wingspan (60.3 meters) than length (59.4 meters). The -200 version of the A340 has typical seating capacity for 250 passengers in a standard layout and a maximum capacity of 420 passengers.

Equipped with four engines that provide 136,000 pounds of thrust (600 kN), the A340-200 is recognized for its ability to cover significant distances, with a range of 6,695 nautical miles (12,400 kilometers). The aircraft's fuel capacity of 155,040 liters (40,957 US gallons) contributes to its long-range capabilities, making it suitable for routes such as transatlantic and transpacific flights. The aircraft's spacious cabin offers comfort for passengers on long-haul journeys, and its four-engine design provides additional reliability over vast oceanic and remote areas.

Competing with models like the Boeing 777-200ER, the A340-200 offered airlines a long-range option with a unique four-engine configuration. Its role in commercial aviation has been defined by its capacity to serve long-distance routes with a medium passenger load, meeting the needs of airlines for intercontinental travel.

The Airbus A340-200 has been operated by airlines such as Lufthansa and Air France, serving as a key component in their long-haul fleets. Only a small number of the -200 remain in service today. Additionally, it turned out that the -300 and -600 versions of the A340 were much more popular.
